Technical Scuba Diving
Intro I knew it would take about an hour to get the photos I needed for a photogrammetry model of the Mavis, but most wreck divers don't want to spend an hour on an airplane. I was fortunate to be diving with Aron / Dirty Dozen and we had an afternoon with nothing specific scheduled [...]
Background One of the challenges of sharing photogrammetry models on-line is that there aren't a lot of sites that allow viewing and uploading of very high definition models. Most of the time, this doesn't really matter. Viewers just want to get a sense of the wreck, move it around, zoom in a few different areas, [...]
Background I had been doing a lot of photogrammetry work on the Saratoga and had one idea that was a "well, if it happens" project. Namely, it would be interesting to build a photogrammetry model of the island (or tower) structure on the wreck. In the photo below, the 5" guns are on the far [...]
Intro This is my 250th post and it is an epic one! Sit back, grab a cup of coffee, and enjoy! Everybody that goes to Bikini dives the USS Saratoga (CV-3) aircraft carrier and there is certainly plenty to see both inside and on the exterior. It is one of only a few dive-able aircraft [...]
This will be a short, but very useful post for anybody who is planning to dive the interior of the USS Saratoga (CV-3) in Bikini Atoll. I was recently on a dive trip to Bikini Atoll with The Dirty Dozen Expedition group and spent a lot of time working on three different photogrammetry projects. The [...]
I recently gave a presentation about some of the new wrecks that Tyler Stalter and I have located and identified. I also discuss how we find them and how we identify them along with some of the tools like photogrammetry. Below is a PDF of the presentation (I've removed two slides that were animations of [...]
I will be presenting at the Long Beach Scuba Show about some of the new wrecks that Tyler Stalter and I have discovered and identified over the past three years in Southern California. The show is on 3-4 June (Sat / Sun) and takes place at the Long Beach Convention Center. My presentation is at [...]
Intro I first wrote about the P-38 in Torrey Pines back in mid-2020. It is a well known wreck that was discovered a number of years ago and has been deteriorating due to multiple factors. After our dive on the deeper P-38 in Solana Beach, we were headed to this wreck. Since I started building [...]
I am very honored to be awarded the Winner in the Wreck Category for the 2023 Underwater Photographer of the Year (UPY) contest. The "photo" that won is a screen capture of the final photogrammetry model I built of the F8F-1 Bearcat that sits 230 feet deep off Point Loma, California. To date, there have [...]
Background I held my first photogrammetry class between Friday, Jan 20th through Sunday, Jan 22nd. This the first time I held the workshop and the results were very good given the conditions we had for the dive day on Saturday, Jan 21st. After a day of lecture and building a model on land, we dove [...]
